I didn’t realize that Maria Snyder’s Souldfinder books, a continuation of the Study series, was indeed the trigger for a cover makeover. At least for the early Study books in Kindle edition. I wouldn’t be surprised if the paperback switch over soon.
Or if the “middle” series in between Study and Soulfinder get a kindle cover makeover.
Personally I like the original covers. I wasn’t a fan of the YA editions they put out, the Kindle covers are a step up from those.
I guess I should feel happy that Snyder’s Study world books are so popular that they keep getting new covers and releases.
